Detailed Description

template <class TScalarType ,
unsigned int NDimensions =3>
class itk::ThinPlateSplineKernelTransform2;

This class defines the thin plate spline (TPS) transformation. It is implemented in as straightforward a manner as possible from the IEEE TMI paper by Davis, Khotanzad, Flamig, and Harms, Vol. 16 No. 3 June 1997
